The first, and undoubtedly, the most important thing is an increase in the rigidity of the profile so much that not only the need for its reinforcement has not only disappeared, but even without reinforcement, the maximum sizes of the wings made of this significantly exceed the permissible sizes of the wings made from a standard reinforced profile. This facilitates the weight of the entire structure by about 40%, which in turn removes most of the load on the linen fittings and extends its service life.
